OpenAI Agents SDK is a lightweight framework for building multi-agent workflows and voice agents in JavaScript and TypeScript.
The framework addresses the need to orchestrate complex interactions between multiple AI agents by providing a unified abstraction layer. It supports three primary agent types: standard agents for text-based workflows, sandbox agents that operate within a filesystem workspace for longer-running tasks, and realtime agents optimized for low-latency spoken interactions. Agents can be configured with instructions, tools, guardrails, and handoff mechanisms to delegate work to other agents. The framework includes built-in support for tool integration through functions and Model Context Protocol, conversation history management via sessions, safety validation through guardrails, human-in-the-loop workflows, and tracing to debug and optimize agent runs.
The tool suits teams building conversational AI systems, automation workflows, or voice-enabled applications in JavaScript or TypeScript environments. Text agents work well for straightforward request-response patterns, while sandbox agents are appropriate when tasks require filesystem access or command execution across multiple steps. Realtime agents enable voice interactions with minimal latency. The framework is provider-agnostic, though it emphasizes OpenAI API integration. It runs on Node.js, Deno, and Bun, with experimental support for Cloudflare Workers.
The project shows active development with regular updates to core functionality and documentation. The maintainers have expanded the framework's scope to encompass voice and realtime capabilities alongside traditional text-based agents. The team maintains comprehensive guides and examples demonstrating each agent type and feature. Development includes beta-stage features like sandbox agents, indicating ongoing refinement of the platform's capabilities.
